To @ZZ whom it may concern,.-

Be it known that we, SILVER PREJEAN and GEORGE CHARLES BELLoCQ, lcitizens of the United States, and residents of Belle Alliance, in the parish of Assumption and State of .Louisiana, have invented a new and Improved Harrow, of which the following is a full, clear, andl exact description.

Our invention relates to anpimprovement in revolving harroWs; and the purpose of the invention is to provide a harrow which will have a wheeled support toarid from the ield and during operation and means whereby the harrow can be kept in one position while rotating relative tvo the rows Betweenyvhich cultivation is to be eected, the construction being, furthermore, such that in operation the harrow will not jump from sidevto side, as is customary in ordinary harrows, vthereby re-K lieving theteam from unnecessary incumbrance and enabling the team to direct all its energy to thedraft of the machine. y,

Another purpose of the invention is to provide means for raising and lowering the cul, tivating medium, so that it may be set `to work shallow or deep and can be elevated at any time to pass over any row of plants with. out injury to them.

f Another purpose of the invention is to pro- Vide an arched axle having long or extended, spindles and Wheels adjustably mounted upon the spindles, whereby the machine may be adapted to narrow or wide spaces betweenl rows and the Wheels adjusted to straddle the rows, thus enabling the machine to be successfully operated in cultivating crops when grown to some height above the surface of the ground Without injury to the plants.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in theclaims. Y

Reference is to be had to the accompanying drawings, forming a part of this specification,` in which similar characters of reference indi-y cate corresponding parts in all the ligures.

Figure 'l is a side elevation of the machine, one of the supporting-wheels being removed.- Fig. 2 is a plan view of the machine, and Fig..

5o 3 is a detail view of the arched axle.

A represents an arched axle, and at the lower portions ofthe downwardly-extending arms of the arched axle bosses 10a are illustrated as being produced, and from these bossesl long-spindles 10 are carried horizon- .tallyoutward A segmental bar 11 extends forwardly from the upper part of the arched axle A,as is best shown in Fig. 2, and the guidepole of the machine is attached at its rearend to the central portion of the upper part of the arched axle A and to the segmental forwardly-extending bar 11.Y The said p ole l2v may be of any'desired length. v, The drivers seatlS is located at the lefthand sideY of thelframe just described, the standard k14 of the drivers seat being preferably secured to the forwardly-extending seg saidloose collars 16 and-17 being held flxedly to the spindles 10 when the Wheels have been adj usted lloy. means of suitable set-screws 18, as is also shown in Fig. 2.

The harrow B is of circular form in plan view and is adapted to rotate as the machine isv advanced. The frame of the said, harrow B consists of a series of radial spokes or bars 19, suitably connected where they meet at the central portion of the harrow, and where the said spokes or bars 19 vmeet an opening is made through which the pivot-pin 20 of the harrow is passed. The said pivot-pin is provided at its lower end with a suitable Washer and nut, as is indicated in Fig. l.

Teeth 2l of any desired typearesecured in p longitudinal order to the radial spokes, bars, or arms 19 of the frame ofthe harrow B, and an inner circular track 22`is attached to" the upper faces of the said arms,. bars, or spokes-.g 19, while an outer concentric track 23 is also attached to the upper faces of the said arms or spokes, as is best shown in Fig. 2.

A draft-tongue 24 extends over the central IOO .portions of the segmental brace-bar 11.

portion of the harrow B from its rear beyond its front portion a suitable distance, and the said pivot-pin 20 of the barrow B is passed through this draft-tongue 24. Where the pivot-pin 2O passes through said draft-tongue 24, a transverse member 25 is formed, and at the forward end of the said draft-tongue a doubletree 26 or a draft-tree of any suitable description is attached, as is shown in Fig. 1. Between the said tongue 24 and the upper face of the harrow B a Washer 27 of suitable size is located, through which washer .the pivot-pin 2O is made to loosely pass, as is shown in Fig. l.

t one end of the transverse member 25 of the draft-tongue 24 a friction-wheel 28 is mounted to freely turn, engaging with the upper face of the inner track 22 at the top of the harrow-frame, and atthe opposite end of the said transverse member 25 of the drafttongue a second friction-roller 29 is mounted to turn, being likewise in engagement with the upper face ofthe inner track 22, while at the rear end of the draft-tongue 24 a frictionroller 30 is mounted to freely turn. This latter friction-roller is in engagement with the upper face of the outer circular track 23. These friction-rollers 28, 29, and 30 serve to hold the rotary harrow B in proper position for eifective service in the ground.

Sometimes it is desirable to have the harrow B rotate in one direction, and at other times it may be advisable to have it rotate in an opposite direction. This guidance in the matter of the rotation of the horrow is brought about by pivoting an arm 32 at its inner end 33 on the draft-tongue 24 at the rear of the transverse member 25, as is shown in Fig. 2, and at the outer end of this arm 32 a friction-roller 3l is mounted to turn, adapted to engage with the upper face of the outer circular track 23, and on the arm 32 adjacent to the friction-roller 3l a weight 34 is secured. When the weighted arm 32 is carried, for example, to the right, bearing upon the harrow, the direct-ion of rotation will be forwardly from the rear, and when the said weighted arm is drawn over so that the friction-roller 31 engages with the opposite side of the harrow the direction of rotation will be rearward from the front.

The harrow B and the connected drafttongue 24 are att-ached to the main or wheelsupported frame of the machine by means of side bars 35, which have a pivotal or hinged attachment to the ends of the transverse member 25 of the draft-tongue, and likewise a pivotal or hinged connection with the underside In order that the harrow B shall not have lateral movement in operation,intermediate connecting-bars 3G are employed, and these intermediate connecting-bars 36 have a link connection 36 at their rear ends with the pivotpin 20, as is shown in Fig. 2, while the upper forward ends of the intermediate bars 36 are pivotally attached to the segmental bracebar 11, preferably at those points where the side bars 35 are likewise attached at their upper forward ends.

The barrow and connected draft-tongue are raised and lowered, so that the barrow-teeth will enter the ground to a greater or less extent and so that the barrow-teeth may entirely clear the ground or be lifted out of engagementwith comparativelyhigh growing plants. This vertical adjustment of the harrow is accomplished by pivotally attaching the ends of a bail 37 to the side bars 35 at a point to the rear of the axle A, and the lower member 38 of an angled hand-lever C is connected with the central portion of the bail 37, the said hand-lever C at the junction of its members being fulcrumed in a suitable bracket 40, supported on the upper portion of the arched axle A. The vertical or upwardlyextending member 39 of the hand-lever C is provided with any approved type of thumblatch 41, which thumb-latch is adapted to engage with a rack 42, supported partially on the axle A and on the pole 12, whereby the hai-row may be raised and lowered as desired and held in its adjusted position.

The extension-spindles 10 of the axle on which the wheels 15 are adjustably held permit the operator to place the wheels at any distance required, in or out, to cause the harrow to work in the middle of the row, no matter how wide or how narrow, while the Wheels straddle two rows. By means of the pivoted arms 36 connecting the draft-tongue and harrow with the wheel-support and by reason of the draft being directed from the center of the barrow the pivotal and draft connections described have a tendency to hold the harrow down to the ground in action, thereby effecting a perfect pulverization of the soil, and at the same time the barrow is prevented from having lateral movement. Consequently the shoulders of the draft-animals are not liable to be chafed, and such animals may exert all their power to draw the machine without inconvenience. The forward .end of the draft-tongue 24 is preferably supported bya chain 43, carried up to an attachment with the pole 12.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The combination with a circular hat-row, of a draft-tongue pivotally connected to the harrow at the center thereof, friction-rollers carried by the draft-tongue for engagement with the upper face of the harrow, and a weighted arm provided with a friction-roller, pivoted to the draft-tongue and adapted for engagement with the upper face of either one side or the other of said harrow for the purpose specified.

2. A wheel-supported frame, aguide-pole for said fraine,a draft-tongue below the frame, a transverse member attached to the draft- IOO tongue, longitndinally-extending side barsu pivotally attachedv at 'their forward ends to the wheel-'supported frame on opposite sides of the guide-pole and at their rear ends to th'e transverse member fof the draft-tongue, the point of connection of said bars with said transversemember being at each sideof the center of said member, intermediate bars 'con-Y nectedat their forward ends to said Wheelsupported frame at points spaced apart from each other, and extending rearwardly and diverging toward each other and.A connected Aat their rear ends with the transverse member of the draft-tongue, between the pointsv .ment of the side bars being at each side of the center of the said transverse member of the draft-tongue, intermediate bars connected with the said wheel-supported frame at points adjacent to the connection therewith of the side bars, the said1 intermediate bars being made to converge at their lower ends,

tongue where the transverse member crosses'v the d raft-tongue, the said harrow being adapted for rotary motion, means for raising and lowering the draft-tongue and barrow, tracks located on the upper surface of the harrow, and' friction-rollers carried by the rear end of the drafttongue and the ends of the transverse member ot' the draft-tongue, the said friction-'rollers engaging with the tracks on the barrow, as described.

4. The combination of a wheel-supported frame, a draft-tongue below the said frame, pivotal connections between the draft-tongue and the said frame, a harrow pivotallyconnectved with the draft-tongue, being adapted for rotary motion, frictionrollers carried by the draft-tongue, for engagement Lwith the upper faceof the hai-row, and a weighted arm provided with a friction-roller, pivoted to the draft-tongue and adapted for engagement with either one or the other side of the l said barrow at its upper surface, for the purpose described.
